Victualling for Future Royal Australia Navy Platforms - Alternative Technologies

Pagination or Media Count:
Rapid Prototyping, Development and Evaluation RPDE are investigating alternative victualling methods for submarines and surface ships of the Royal Australian Navy RAN. Emerging food processing technologies were identified and considered in the context of the RAN victualling system and naval food culture. Technologies such as cook chill - heat treated refrigerated food HTRF - have a shelf-life up to 2 months and are currently available. Other technologies, such as high pressure processing HPP and microwave assisted pasteurisation MAPs promise fresh-like foods with extended shelf-life under chilled storage. While other developing technologies such as microwave assisted thermal sterilisation MATS and high pressure thermal processing HPTP aim to produce extended shelf-life foods which are fresh-like and shelf-stable. Although the technology readiness levels TRLs of the emerging technologies estimated to be 6, key decision dates of some future naval platforms are still about 5-10 years away. These technologies might then reach maturity within this timeframe. Opportunities, risks and mitigation strategies are also discussed.
